It didn't use much oil or any it was still midway on the dipstick. I have 2 recalls to do on my car, so I'll show pics to the Ford Nuts while they have my car all day and let them look further into it. My MPG is 30 but I don't drive very eco, I do open it up a lot. This car is fast as my 400HP Truck, but if I pulse and glide I get 40 MPG
